Alciato's Book of Emblems

Emblem 3

One ought never to procrastinate

The elk raises the sign of the Alciato family, and it bears
in its hooves "Never postpone anything". It is known that
Alexander answered thus to one who asked him how he had
accomplished so many deeds in a short time. By never being
willing to delay, he said. And that is the meaning of the
elk, for you might wonder if it is stronger, or swifter.
